摘要

Pau Branco矿山为两座高炉提供铁矿块，目前生铁生产的木炭消耗占高炉运营成本的47%。提出了一个地质冶金模型，以支持基于不同类型铁矿石冶金性能的储量、产品质量和运营成本的经济研究。样本分析提供了模型所需的值。根据该模型，提出了一种替代生产计划，对采矿/磨矿系统的当前净现值产生2560万美元的积极影响。

Mine/Mill production planning based on a Geometallurgical Model

The Pau Branco mine supplies two blast furnaces with iron ore lumps, and currently, charcoal consumption for pig iron production accounts for 47% of the blast furnaces' operational cost. A geometallurgical model is presented to support an economic study considering reserve volumes, product quality, and operational costs based on the metallurgical performance of different iron ore typologies. Sample analysis provides values required in the model. From the model, an alternative production plan is presented with a positive impact of USD 25.6M over the current net present value of the mining/mill system.

期刊介绍： REM – International Engineering Journal (antigua REM – Revista Escola de Minas) es la primera revista técnica de Sudamérica. Fue fundada en enero de 1936 por los estudiantes de la Escuela de Minas de Ouro Preto y desde entonces se ha especializado en la publicación de artículos en las áreas de la Ingeniería Civil, Geología, Metalurgia y Materiales y, Minería y Mecánica y Energía. Su objetivo es servir como un medio de publicación para los trabajos técnicos y científicos originales de investigadores nacionales y extranjeros en esas áreas. Contribuciones originales (artículos y cartas) son aceptadas. Artículos de revisión dependen de la invitación y/o análisis de los Editores. El envío de artículos para su publicación implica que el trabajo no ha sido publicado previamente, que no está siendo presentado para su publicación en otra revista y no se publicará en otro lugar, en la misma forma, sin el permiso, por escrito, de los Editores/Autores.
